In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a steel wheel hub center lid, includes the lid, be equipped with a plurality of nut mounting holes on the lid, the back of lid corresponds nut mounting hole department extends and is equipped with the erection column, the lower extreme of erection column is equipped with the flexure strip that is circumference evenly distributed more than three, the first cavity of back taper is enclosed to the flexure strip, form columniform second cavity in the erection column, first cavity and second cavity intercommunication. The utility model discloses the principle: attaching the central cover to the central hole of the steel wheel hub, and aligning the nut mounting hole with the steel wheel mounting hole; the bolt is inserted into the mounting column from the mounting hole of the steel hub, and then the nut is placed into the mounting column through the nut mounting hole and matched with the bolt; after the bolts are locked by rotating the nuts, the steel wheel hub and the wheel shaft can be fixed, and the decorative cover can also be fixed on the steel wheel hub; because the elastic sheet encloses into conical first cavity, the cone head of its front end is in first cavity and extrudees the elastic sheet after the nut locking, consequently can play the purpose of fastening the center lid, can not influence steel wheel hub's locking, can not lead to the center lid fracture because of the nut locking force greatly yet.
As an improvement, the cover body, the mounting column and the elastic sheet are integrally formed by injection molding.
As an improvement, the lower end of the mounting column is provided with four elastic sheets in total.
As an improvement, the lower end of the mounting column is connected with the elastic sheet through an annular boss.
As an improvement, the back of the cover body is provided with limiting columns between adjacent nut mounting holes, and the bottom surfaces of all the limiting columns are combined to form a limiting plane.
As an improvement, the limiting column is cylindrical or U-shaped.
Compared with the prior art, the utility model the beneficial effect who brings is:
after the bolts are locked by rotating the nuts, the steel wheel hub and the wheel shaft can be fixed, and the decorative cover can also be fixed on the steel wheel hub; because the elastic sheet encloses into conical first cavity, the cone head of its front end is in first cavity and extrudees the elastic sheet after the nut locking, consequently can play the purpose of fastening the center lid, can not influence steel wheel hub's locking, can not lead to the center lid fracture because of the nut locking force greatly yet.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, a steel hub center cover 2 can be made of a nylon material with good temperature resistance; as shown in fig. 3, the hub center cover 2 includes a cover body 21, the cover body 21 is provided with a plurality of nut mounting holes 22 uniformly distributed on the circumference, the nut mounting holes 22 are used for accommodating the nuts 3, and the nut mounting holes 22 correspond to the steel hub mounting holes 11 one to one; as shown in fig. 4, a mounting post 25 extends from the back of the cover 21 corresponding to the nut mounting hole 22, two ends of the mounting post 25 are communicated, and more than three elastic pieces 23 are uniformly distributed on the circumference of the lower end of the mounting post 25, in this embodiment, the lower end of the mounting post 25 is provided with four elastic pieces 23; the lower end of the mounting column 25 is connected with the elastic sheet 23 through the annular boss 24, the elastic sheet is enclosed into an inverted cone-shaped first cavity, a cylindrical second cavity 27 is formed in the mounting column 25, and the first cavity is communicated with the second cavity 27; the cover body 21, the mounting post 25 and the elastic sheet 23 are integrally formed by injection molding.
As shown in fig. 4, a limiting column 26 is arranged on the back of the cover 21 between adjacent nut mounting holes 22, and the bottom surfaces of all limiting columns 26 are combined to form a limiting plane; the limiting column 26 is cylindrical or U-shaped; the limiting column is designed into a hollow structure, so that the design has the advantages of having certain elasticity, avoiding other elastic pieces from being broken due to overpressure, and having the function of a 'cushion' like other elastic pieces; the bottom surface of the limiting column 26 is in contact with the surface of the steel hub 1, so that the limiting effect is achieved.
As shown in fig. 5 to 7, the nut 3 of the present embodiment preferably comprises a tapered head 31, a stainless steel coating cooperating with the upper part of the nut, and a flange 32. After the nut 3 is placed in the mounting column 25, the conical head 31 is placed in the first cavity, is matched with the elastic sheet 23 which is arranged in a conical manner, and achieves the purpose of fixing the central cover by extruding the elastic sheet 23; the flange 32 of the nut can cover the gap between the annular boss 24 and the adjacent elastic sheet 23, and the appearance is more beautiful.
The utility model discloses the principle: attaching the central cover to the central hole of the steel wheel hub 1, and aligning the nut mounting hole 22 with the steel wheel mounting hole; the bolt is inserted into the mounting column 25 from the mounting hole of the steel hub 1, and then the nut is placed into the mounting column 25 through the nut mounting hole 22 and matched with the bolt; after the bolts are locked by rotating the nuts, the steel wheel hub 1 and the wheel shaft can be fixed, and the decorative cover can also be fixed on the steel wheel hub 1; because the elastic sheet 23 encloses into conical first cavity, the cone head of its front end is in first cavity and extrudes elastic sheet 23 after the nut locking, consequently can play the purpose of fastening the center lid, can not influence the locking of steel wheel hub 1, also can not lead to the center lid fracture because of the nut locking force is big. The manufacturing error all exists in center lid and steel wheel, and the assembly is not hard up or excessive pressure fracture problem appears easily under this kind of condition, in order to avoid this kind of problem, considers to have interference fit, under the certain magnitude of interference circumstances of having designed, when the pressure equipment nut, except four cylindric flexure strips, spacing post also possesses elasticity and buffer function to can guarantee to cover the performance that the center lid neither becomes flexible nor appears the fracturing.
